Liva is built to cost car with class leading cheap interiors(be it dashboard or seats). Any day the new Swift is 100 times better than this car. New swift is well built and has acceptable level of quality. Already there are complaints of water leaking into the etios due to absence of rubber cladding on the doors.
In terms of looks - Swift wins hands down. Liva is a simple design does not inspire any awesomeness
In terms of interiors - Swift wins it again. Although coming from a brand known of quality, Liva is full of cheap material and feels flimsy
In terms of engine - Swift wins this one too. It is more planted, driveable, peppier, gives better FE, and has better gearbox and braking.
